We compared our method, which we will refer to as the Hybrid method, against 1) a plain vanilla U-net [1]} with a residual connection, referred to as UNET; 2) RefineGAN [2]}; 3) DAGAN [3]}; and 4) Deep-Cascade [4]} with a cascade of five CNNs and five DC blocks, which is the network configuration that the authors reported best results.
